Great price and quality. I could not program this myself!!! I do believe you have to have a special programmer or have it programmed by a professional. So here is what I learned and hope it helps, the local car dealership wanted to charge me over $300 to program, batteries plus was $85 and what we used was a locksmith who only charged $75 and had it done in minutes.

The media could not be loaded. I don't normally write reviews unless I'm really happy with product or to many uncertain reviews so here is mine. 2008 g37s coupe. Lost my key. Bought 1 to see if I could program it to work. Had a guy come program it with xtool tablet. It worked. So I bought 2 more so now I have total of 3 of they with the chip in the key (that's important) that's what that little screw there is for. And I have personally programmed the other 2 myself meaninging I had to erase the original and program them all together.THEY WORK! save $100 per key to be programmed plus the cost of a $80+ key from infiniti. But I haven't got the keys cut. So aside from that this was a successful buy and I hope my review genuinely helps others!

I purchased this with the idea that I could just take the circuit board out of my old key fob and install it into this one, and I'd be set. My original key fob's plastic keys were cracked, broken or worn out. So, no problem right? - just open up the old and transfer to the new! NOPE.I open this replacement up, remove the circuit board and the first thing I notice is (1) that the rubber protector between the keys and board has a flaw where the rubber doesn't extend all the way to the plastic, meaning liquid could intrude should the fob get wet.(2) I swap out the aftermarket board with OEM and I cannot close the two halves together, it is as if something is keeping it separated on one side. I inspect it trying to figure out what the problem is, the replacement plastic looks pretty much the same as the OEM one. I try to transfer the rubber sheet beneath the keys over from the old to new, the back cover from the old to the new (they're different in that they don't snap together), I even look at taking the new plastic keys out from the new one and transferring them to the old (you can't, different design).(3) In the end, it would appear that the "new" chinese circuit board is slightly thinner than the old and the OEM thicker one doesn't have clearance for the halves to close. The board on the replacement has far less components but that doesn't hinder anything since there is space for the components on the original board. I cannot figure out what exactly is causing the old one to not close but I have it close enough to closed as long as the key is inserted to prevent the end from flying open.(4) After all that, you can't use the original key with this "replacement" housing since it won't keep the end closed, you have to use the blank it comes with to keep the end closed.So this isn't really a replacement fob if I can't replace my original plastic by swapping electronics or use the original key, it's just a cheap chinese fob that, judging by the simple circuitry compared to OE, you may or may not be able to program to use with your car.

Great product. Was able to program easy and cut well

Good quality , but a pain to program. Programming cost a large some of money, but the key is significantly cheaper than the key the locksmith wanted to provide.

Good key but idk if it was the key or the programmer but didn’t always work

One of the two key fobs worked.

I have purchased a few of these fobs only to find out from the dealer that they are not programmable. This particular one however does take the programming and that makes it a winner.
